The invention relates to improvements in ski binding as described in thepresent specification and shown in the accompanying drawings that formpart of the same.

The invention has for its general object the provision of an adjustableski binding that can be readily set to diiierent sized boots. Moreparticularly, however, the invention aims to provide a binding that inaddition to its being adjustable laterally of the ski to accommodatedifferent widths of boots, is capable of angular variation to adapt itto varying toe angles. This is highly advantageous in that it enablesthe binding to be set to conform snugly to the sides 3.5 of the boot.Another advantage which this invention presents is that this form ofbinding can be manufactured of metal stampings, which is inexpensive andadds to its substantiality and serviceability. An even still furtherdistinctive feature which this invention possesses is the facility withwhich it can be fitted to a ski and adjusted to a given size of boot.

The invention consists of the novel construction and arrangement of theski binding possesszo ing the above mentioned characteristics, hereafterdisclosed in detail and claimed in the appended claims.

Referring to the accompanying drawings: Figure 1 is a side elevation ofthe invention .50 shown fitted to a conventional ski.

Figure 2 is a top plan view thereof depicting the underplates in asecond position in dot-anddash lines:

- Figure 8 is a slight modification of the underri) plates.

Figure 9 is a plan view similar to Figure 2 but showing a furthermodified form of the invention.

, Like numerals of reference indicate corresponding parts in each of thefigures throughout the drawings.

In recounting the invention reference will first be had to Figures 1 to5 inclusive. The conventional wooden ski to which the binding isattached, is depicted at 10 and the heel pad is shown at 11.

In carrying out this invention a pair of metal under plates 12 areemployed together with a metal top plate 13. The underplates are bent upat right angles forming wings 14. It is to be understood that the wingsshall have ears to fit over the edge portions of the boot sole, or beequipped with toe straps for which purpose the apertures 15 aresupplied. This, however, does 6| not concern the present invention.

The body of each underplate is fashioned with a pair of spaced elongatedslots 16 transversely directed as shown. The sides of these slots areinclined or sloped and supplied with teeth or other forms of serrationsas at 17.

The top plate 13 is fashioned with indents or tits 18, four in number,one for registering with each of the slots 16. These indents arestruckup out of the metal and located on the reverse side of the topplate so as to engage in the respective slots aforesaid. The indents arepreferably of a circular configuration and have inclined or slopingwalls corresponding to the sides or" the slots and likewise suppliedwith teeth or other forms of serrations as at 19.

The slots permit of the underplates being adjusted inwardly or outwardlyof the top plate and laterally of the ski 10; whereas the teeth of theslots interfit with those of the indents to 35 lock the underplate inany position in which it may be set. To adapt the underplates to a largeboot, they are of course shifted outwardly as indicated in dot-and-dashlines in Figure 2; however in some cases the angle of the receding toeportion of a boot also varies and consequently the angle of the wingsmust be changed to suit. This is achieved by shifting one indent of anunderplate a notch or two without changing the position of the otherindent. This is 95 a salient feature of the invention as it has beenfound in actual practice that sufficient angular adjustment can beobtained as well as lateral extension to take care of the usual range ofsizes of ski boots. 160

The top plate is screwed down on the wooden ski 10 in order to clamp theunderplates against movement. This is preferably accomplished byfurnishing the top plate with flanges 20 offset slightly less than thethickness of the underplates. The flanges are apertured to receive thewood screws 21.

It is desirable to employ a centre screw 22 fitted in an indented hole22' in the top plate for the purpose of locating or setting theunderplates in fitting the binding to a particular boot. The metalaround this screw is cut away on each underplate as denoted at 23 inorder that it may not obstruct. It will also be observed that the frontand rear edges 24 are made circular to permit of the necessary angularmovement.

it will be manifest from the preceding description that the underplatesmay be readily adjusted or re-adjusted and when properly set aresecurely locked by the engagement of the indents in the slots in thescrewing down of the top plate.

Adverting to the variant form of top plate shown in Figures 6 and 7, theflanges are dispensed with and the screws placed in the indentures ofthe indents 18 by the provision of a central hole 25 in each of them.

In the modification shown in Figure 8 an un derplate is shown witharcuate slots 26, both of which slots are curved on radii taken on acommon centre outside of the plate. This curvature enables theunderplate tochange-its angle as it is shifted to correspond to theangle of the toe of the boot to which it is adapted.

' The modification depicted in Figure 9 illustrates the underplatesfashioned with inclined or sloping teeth 27 along the front and rearedges, which are made straight instead of curved. Indents 28 are formedon the top plate and have rounded oif faces serrated for engagement withthe teeth 27 respectively of the underplates. The screwing down of thetop plate secures the underplates as previously recounted.
